Application filed'March 9, 1911. Serial No. 613,426.

To all whom it may concern:

Be it known that I, WILLIAM LINDSAY HAMILTON, a subject of the King ofGreat Britain and Ireland, residing at 39 Bothwell street, Glasgow,Scotland, have invented new and useful Improvements in or Connected withMeans for Tipping Rail-Supported lVagons and the Like, (for which I havemade application for patent in Great Britain, No. 19,574, bearing dateAugust 22, 1910,) of which the following is a specification.

This invention which relates to means for tipping rail supported wagonsand the like, is devised for the purpose of discharging material out ofwagons supported by an elevated track, and is particularly adapted foruse in systems in which material is required to be conveyed to a storageground or other place and discharged at one place, or discharged atpositions which are periodically advanced so that the dischargedmaterial accumulates upon the ground in the form of an advancing bank;the invention is alsoadapted for use in forming railway and otherembankments.

According to this invent-ion, an elevated railway is provided to extendover the area upon which the material is to be discharged, upon whichthe wheels of carriages depending from the railway are adapted to run,and at a station where the discharge is to be effected the railway isfurnished with means adapted to enter into working engagement withmechanism for tipping or inverting each carriage as it enters thestat-ion, associated, if required, with means for returning the carriageto its upright position as the carriage passes out of, or after it hasleft, the station; and in order to effect the discharge at successivepositions provision is made whereby the station may be advancedprogressivelv and the continuity of the railway maintained. 1

Some examples of construction and application of means according to thisinvention will now be described with reference to th accompanyingdrawings, in which 5- v Figure 1 is a side elevation of a portion of anelevated railway arranged and furnished according to this invention.Fig. 2 is a side elevation, drawn on a larger scale, of a carriersuspended from the railway in its upright position with a wagon mountedtherein, Fig. 3 is an end view of Fig. 2 showing the railway of Fig. 1in cross section, and

Fig. 4 is a, side elevation, corresponding to F1g 2, showing the carrierin an advanced posltlon on the track with the carrier tilted fordischarging the contents of the wagon.

Fig. 5 is a side elevation partly in section, and Fig. 6 is a crosssectional end view of a form of aerial or suspended railway associatedin a construction according to this invention. Fig. 7 is a sideelevation of a railway of the type illustrated at Figs. 5 and 6; andFig. 8 is a plan of an endless railway of the same type, arranged andfurnished according to this invention. Fig. 9 is a cross section andFig. 10 is a longitudinal section of a track furnished with a rack.

The elevated railway arranged andfurnished as shown at Figs. 1 to 4,comprises standards A carrying two cables B B in suspension, spacedapart and arranged parallel to one another. From each cable links Cdepend, their lower ends being fixed to a series of rigid rails Dcoupled together, forming a railway having a double track upon which thewheels of carriages, depending from the railway, are adapted to run.

In the forms of construction illustrated, at the station on the railwaybeneath which the discharge is to be made, one of the tracks isfurnished witha rack E, projecting from the underside of therail D. Foruse in association with a track of this description, carriages, orcarriers for wagons, hereinafter referred to as carriers and geneallydesignated by the letter F, are provided, comprising in construction aframe F upon which the wagons are adapted to be wheeled and fixed whenin position, and furnished with means such, for example, as a toothedwheel G adapted, as the carrier advanced, to enter into engagement withthe rack E at the discharging station and by rotation impart a turningmovement to the frame F so that the wagon is inverted or tippedsufliciently to discharge its contents. After discharging, the carriermay be drawn back, or it may be further advanced, and in either case themeans may be arranged to act, or permit the frame F to be returned to orto assume its upright position. In' the form of construction shown atFigs. 2, 3 and 4, the turning motion is transmitted from the toothedwheel G, which engages with the rack E to the frame F by means of achain I-I operating a toothed pinion H fixed on the axle, of the frame Fthe axis of which is transverse to charge, or it may be used in caseswhere the frame tends to assume its upright position after the wagon hasbeen discharged. A modification of this form of gearing is shown atFigs. 2, 3 and 4, for use in a system where the direction of travel ofthe carrier is not reversed and in which the frame is tilted in onedirection and then by a reverse motion brought back to its uprightposition. This system is particularly adapted to be embodied in theconstruction of an endless track as indicated at Fig. 8. In themodification shown at Figs. 2, 3 and t, the motion transmitted by thegear wheel G engaging with the rack E turns the frame from its uprightinto its inverted position for discharging the contents of the wagon,the frame being returned to its upright position by operation through anauxiliary gear wheel G arranged to engage with an auxiliary rack E whichtransmits a reverse motion to the shaft on which the gear wheel G ismounted. The racks E and E and their complementary gear wheels G and Gare set in different paths relative to the run of the track so that thegear wheel G which engages with the rack E passes clear at the side ofthe rack E and the gear wheel G which engages with the rack E passesclear at the side of the rack E.

- The rack E may conveniently be placed some distance in advance of therack E, but they may be placed close together if desired.

This invention is particularly adapted to be associated in constructionwith aerial or suspended railways of a known type, an example of whichis shown at Figs. 5 and 6. This type of railway may comprise a single ora double line of rails for the wheels of the carriers to run on. Theexample illustrated has a double line of rails, and comprises twolongitudinal assemblages of sections, each section being formed with acontinuous yoke J to rest upon a cable K in suspension, and having acontinuous suspender J depending from the yoke and a continuous way D,supported by the suspender, for the wheels to run upon, the arrangementbeing such that each section is wholly supported throughout its lengthby resting upon a cable in suspension and every portion of the line issupported by direct suspension from its cable, and the sections, ofwhich there is a series coupled together in each assemblage, have somefreedom of angular movement relative to one another. A more detaileddescription of the type of railway in question is contained in thespecification of W. L. Hamiltons Patent No. 978581 dated 13th December,1910. In application to railways of the 1V. L. Hamilton type as definedgenerally with reference to Figs. 5 and 6, any longitudinal sectioncomprised in the formation of the track may be furnished with a rack Ehaving a series of teeth sufficiently long to impart any of the motionsrequired to be given to the carrier. In practice, the rack E may in oneform of construction be fitted to the section, and be located, for eX-ample, on the underside of the way of the section, and in order toenable a rack to be placed at any position along the line, provision ismade for fastening a rack at any station, for example, by bolts, theline having appropriate apertures or fittings for the purpose.

In aerial systems of. the description in question where the carriers aredrawn along and returned in the same direction, the track, as indicatedat Fig. 7, need not be completed beyond the station, but it may beconvenient to furnish a part in order to support the carrier ifoverhauled beyond the station. To permit the station to be advanced instages progressively, a series of longitudinal sections may be providedadapted to be inserted and assembled with the other sections on thecable or cables.

lVith the object of insuring that the toothed wheel G or G may morereadily enter into mesh with the rack, the initial tooth of the rack, asshown at Figs. 9 and 10, may consist of a roller L, but in the form ofconstruction shown instead of the initial tooth only consisting of aroller all the teeth shown are composed of rollers.
